Solution Overview
Problem
Conventional transformers with non-integer winding turns suffer from unbalanced magnetic flux and reduced conversion efficiency due to asymmetric magnetic field distribution, leading to heat issues and decreased performance.
Innovation Solution
A multiple winding transformer design featuring a core unit with N windings in the first set wound sequentially and overlappingly, where each winding's input and output terminals are spaced 360/N degrees apart, interconnected to form input and output ends, and a second winding set wound around the core, reducing power consumption and improving efficiency by decreasing the number of turns to 1/N of the original.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the number of winding turns is reduced to achieve non-integer ratio for optimal efficiency, then conversion efficiency is improved, but magnetic field distribution becomes asymmetric causing unbalanced magnetic flux
Solution Approach 1:
The primary winding is divided into N separate windings (where N≥3), each with 1/N of the original turns. These segmented windings are distributed around the core at equal angular intervals (360/N degrees), transforming a single unbalanced winding into multiple balanced windings that collectively achieve the desired non-integer turn ratio while maintaining symmetric magnetic field distribution.
Solution Approach 2:
Each individual winding in the set has localized characteristics optimized for its specific position on the core. The windings are arranged with specific angular spacing (360/N degrees) to create locally optimized magnetic paths, where each winding contributes to the overall balanced magnetic flux distribution while maintaining the reduced turn count for efficiency.
2Stability of the object's composition
If conventional integer winding turns are used, then magnetic field distribution is symmetric, but conversion efficiency cannot be optimized for non-integer ratios
Solution Approach 1:
Instead of using a single integer winding, the design segments the winding into N separate windings distributed around the core. This segmentation allows the system to achieve non-integer effective turn ratios while maintaining the symmetric geometric arrangement necessary for balanced magnetic field distribution.
Solution Approach 2:
The solution transitions from a one-dimensional sequential winding approach to a multi-dimensional spatial arrangement. Windings are distributed around the core in three-dimensional space with specific angular spacing, adding a spatial dimension to the winding configuration that enables both symmetry and non-integer ratio optimization.
3Use of energy by stationary object
If N windings are used with reduced turns to achieve 1/N^2 power consumption reduction, then power consumption decreases, but device complexity increases
Solution Approach 1:
The N individual windings are electrically connected in parallel to function as a single unified winding set. This merging of multiple windings into one equivalent electrical component achieves the power consumption reduction (1/N^2) while presenting a simplified interface to the rest of the circuit, effectively combining multiple complex elements into one functional unit.
